,This invention relates to improvements in heating apparatus, forexample stoves, and it consists of the constructions, combinationsandarrangements herein described and claimed.

An object of the invention is to provide a hood or superheaterA for astove or any other kind of circulating heater-said hood l beingincorporated therein in such a inanner as to cause the greater volume ofincomi air tofollow the contour of a'highly heated drum, said hoodhavingan openin or openv ings at the .top through which t e`heated is shown to'have a top 10 which is perfoh 12' for the egress of.

a1r yis discharged at a considerable speed,

thereby insuring the heating of the room 1n a rapid and uniform manner.

. Other objects and advantages appear in the following specification,reference beiner had to the accompanying drawing, in which Figure 1 is aperspective view of the Stove 1n use. I 4

Figure v2 is a lcentral vertical section.l Figure-3 is a detailperspective view of the hood.

In carrying out the invention provision is made of a fire pot orbowl 1having an appropriate type of grate 2 upon which the pot, andthe drum issurmounted by a semiglobular dome'4 from which the products ofcombustion escape by way of. the` pipe 5 to an appropriate flue. The'fire pot drum 3 and dome 4 constitute they-central body or heatingelement of the stove which is-enti'rely closed so far as the immediatelysurrounding heating space isconcerned.

The fuel is. introduced into the stove through a char 'ng door 6 andashes are removed from t e pit 7 through a door 8. The shell 9constitutes the outside jacket which is designed along such lines as togive the stove theydesired appearance as illustrated in Figure 1'. Herethe jacket rated both at 11 'and heated air.

Brackets 13 support a tubular imperforate heat screen, or partition 14in spaced relationship to the drum 3. Other brackets 15, secured at 16to the `the hood 17 orso-called superheater in rspaced relationship tothe .dome 4. The

hood has an opening or openings 18 through which air admitted at anappropriate opening19 in the bottom4 of t e stove escapes dome 4supports after having been forced to follow the contour of the drum 3and dome 4 by the parv tition 14 and the hood 17. The 'latter is'situated in the heating space mentioned be fore. The hood has a notch-20which --fits over the y smoke pi e 5. space between the Ahood 17 an Ithedome 4 is'greater than the space between the par- (Fig. a)

tition 14 and the ,drum 3 for reasons which` appearing'in the following'Operation.

As stated before, the cool air is admitted into the'heating space' ofthe stove through. an appropriate ,opening 19 in the bottom (Fig. 2).The partition 14 and hood 17 are intended tol cause 'the greater'."volumc of incoming air to follow the contour yot the heating element.The partition 14 is closerk to the drum 3 than it is to the shell` 9,thereby making the space on the outside of the partition somewhatdeeper` than the space, on the inside. But the lvolume of air passing'through the inner space is intense y.heated, because it repre-l sents athinner layer and passes directly It has also been stated that the spacebetweenl the Idome 4 and hood 17 is greater than the space between thedrum 3 and ar.-

' the partition 14 but also some-of the air from the outer s ace. It isnow Aapparent that the space wit in the hood may be made somewhat largeras it receives double por-A tions of air. l

But the hood also follows the contour of the dome 4, and by virtue ofthis fact the,

air received thereby is subjected to the very ot dome and furthermorevhas imparted thereto considerable velocity which sends it directlyupward through the o ening 18 and out of the p'erforations 12. thervolumes of air, not subjected to the foregoing extreme heating actionescape at the perforations 11, but the ultimate result is that all ofthe heated airpasses upwardly in the room.

By virture of the fact that the air is sube to a vigorous lheatingaction and ejected ond the screen so that the space- The over rthe drum3 which, presumably, is very coals are supported. The tubular drum 3 hconstitu-tes an upward,V extension of the lire With an equally vigorousaction, the

lllA

room becomes heated both quickly and uniformly. It is an obvious resultthat if more of the heat units of they fire can be utilizedl for theuseful purpose of heating the air the stove in which the foregoingprinciple is embodied becomes more eflicicnt than other stoves. And afurther result must necessarily follow that a substantial saving in fuelw11l be had.

While the construction and arrangement of the heating apparatus is thatof a generally preferred form, obviously modifications and adaptationsin the form thereof herein described may be made without departing fromthe spirit of the invention or the scope of the appended claims.

1. Heating apparatus comprising a heating element which includes atubular drum and a substantially semi-globular dome having a lateralsmoke outlet pipe, a shell constituting the outside jacket of theapparatus having air inlet and outlet openings, an

open ended tubular partition in concentric spaced relationship to thedrinn` a hood shaped substantially like the dome but being' spacedfarther therefrom than the partition is spaced from the drum leaving acircumferential opening for the ingress of air from the space at bothsides of the-partition, said hood having a notch fitting over the outletpipe and "a top central opening aligning with the shell outlet openingfor the esca e of heated air, and means for simultaneous y supportingthe partitionv and hood, said means including brackets carried by thedrum and other brackets' carried by the dome.

2. In combination with a combustion chamber having av dome at the top,supports radiating therefrom, a centrally orlced hood placed upon saidsupports in spaced relationship to the dome providing a circumferentialair inlet at the lower` edge thereof for directing the air passing upthe side of the combustion chamber' and into said inlet acrossthe top ofsaid dome. l

3. 1n combination with a combustion chamber, a dome closing the top,contiguous supports radiating from both the combustion chamber anddomethe latter supports being longer thanthe former, a (partition.

depending from the shorty supports being open at the bottom and top, anda centrally oriiiced hood placed upon the long supports being spacedfarther from the dome the partition is spaced from the combustionchamber thereby defining a circumferential air inlet at the lower edgethereof both inside and outside of the partition.
